Electromagnetic immunity declaration
The Pump is intended for use in the electromagnetic environment specied below. The
customer or the user of the Pump should assure that it is used in such an environment.

guidance
Portable and mobile RF communications
equipment should be used no closer to
any part of the Pump, including cables,
than the recommended separation
distance calculated from the equa-
tion applicable to the frequency of the
transmitter.

Field strengths from xed RF transmitters,
as determined by an electromagnetic site
survey,
a
should be less than the compli-
ance level in each frequency range.
b
Interference may occur in the vicinity of
equipment marked with the following
symbol:
R
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is aected
by absorption and reection from structures, objects and people.
a
Field strengths from xed transmitters, such as base stations for radio (cellular/cordless) telephones
and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be
predicted theoretically with accuracy. To assess the electromagnetic environment due to xed RF
transmitters, an electromagnetic site survey should be considered. If the measured eld strength in
the location in which the Pump is used exceeds the applicable RF compliance level above, the Pump
should be observed to verify normal operation. If abnormal performance is observed, additional mea-
sures may be necessary, such as reorienting or relocating the Pump.
b
Over the frequency range 150 kHz to 80 MHz, eld strengths should be less than 13 V/m.
